Bad Luck Bolshevik or Scumbag Soviet?

Mikhail Tukhachevsky was a forward thinker who posited in the 1920s and 1930s that tanks would reign supreme on the battlefield instead of traditional horse cavalry. For this (and a myriad of other reasons) he was tried, convicted of treason and deliberate wrecking, and shot.
Couldn't have happened to a nicer guy though; during his rise to power he allowed for the execution of POWs and use of chemical weapons against civilians without batting an eye.
